What Is IAQ and Why It Matters

Indoor Air Quality (IAQ) refers to the condition of the air inside buildings—especially how clean or polluted it is and how it may affect the health and comfort of people inside. Many people think of pollution as an outdoor problem, but the truth is, indoor air can often be 2 to 5 times more polluted than outdoor air. This matters because we spend about 90% of our time indoors, breathing in air that could be filled with dust, chemicals, mold spores, allergens, or other irritants.

Poor IAQ can have immediate effects like coughing, sneezing, eye irritation, or fatigue. But over time, it can also contribute to more serious conditions—especially for people with asthma, allergies, or immune system issues. Children, the elderly, and those with chronic illness are particularly sensitive. By understanding what’s in our air and how to improve it, we take a powerful step toward protecting long-term health and creating a home that supports healing and wellness.
